If a macro is used with too few parameters, complaining about its
definition using '#' followed by something other than a macro
parameter name is apt to be confusing - reading the definition will
reveal that the name in fact is a macro parameter after all. The
reader needs attention directed to the invocation, not the definition.
Split the test in two: one to test the prior error message does in
fact get produced for an invalid macro definition, the other to test
the invalid invocation case.

reading a whole file into memory just to create a slightly modified
copy of it.
For this small test case:

class X : public QObject { Q_OBJECT Q_PROPERTY(int x) };
EOF
massif shows improvement from:
peak cost: "26,8 KB" heap "2,1 KB" heap extra "0 B" stacks
to:
peak cost: "11,3 KB" heap "2,2 KB" heap extra "0 B" stacks
In general, depending on source file high peak memory usage is reduced
from few to few hundreds KB, especially that the allocation used to
happen for each include file too.

The byte array literals are only used to append them to another
QByteArray, so they offer only the static size calculation as a
benefit.
However, there are several drawbacks:
- QByteArrayLiteral data cannot be shared the way string literals
can be, not even within a single TU, and they add a few ints
for the QByteArrayData header which cannot reside in BSS, but
need to be stored in DATA.
- QByteArrayLiteral *does* allocate when the compiler doesn't
support C++11 lambdas.
- QByteArrayLiteral, when not using RVO, litters the code with
QByteArray dtor calls, which are not inline, and thus can't
be optimized away.
In particular, when used like this, they do not prevent any
memory allocation (in fact, they might add some, absent lambdas).
So, just append (C) string literals.
